It's a ARP 2600 sound.The source of the click is OSC 1 that's set to LF range. And in the VCF the OSC1 default square slider is set to max. The reverb is set to max too.

I don't know if this is intended or if the preset has been corrupted at a time. I think it's an old preset. It's a bit strange as it is. But only the JMB know if it was intended - perhaps to add some mystery to the sound.

Perhaps the range was set to a audioble range at a time. But then the sound is different from now.To keep the sound as it is now, but without the click the OSC1 slider in the VCF should be set to zero. But you can't change that in Analog Lab 2.(You can't change the range either in Analog Lab.)You can only remove the click yourself, if you have the full ARP 2600 application.

As it can be a mistake in the sound, then i attach the sound where i have removed the click. Just import it into Analog Lab 2. If Arturia don't wan't this, then fell free to remove the preset from this post.
